Abstract

L'invention concerne une pompe médicale pourvue de : un écran tactile susceptible d'afficher des informations et de détecter une opération d'entrée par un opérateur ; et une unité de commande qui commande l'état de réception de l'opération d'entrée par l'opérateur et qui est susceptible de réaliser un traitement d'opération de réglage lié à des réglages et des opérations sur la base de l'opération d'entrée par l'opérateur. L'unité de commande effectue un traitement pour commuter l'état de réception entre un état verrouillé dans lequel le traitement d'opération de réglage basé sur l'opération d'entrée n'est pas effectué, un état déverrouillé dans lequel le traitement d'opération de réglage basé sur l'opération d'entrée est effectué, et un état verrouillé temporaire qui est un stade de transition de l'état verrouillé à l'état déverrouillé.
